Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibrating apparatuses for conveying small objects in the chemical, cosmetic, and pharmaceutical sectors generate friction, leading to particulate matter production, are rigid and costly to reconfigure, and require bulky frames for damping, making them unsuitable for aseptic environments and difficult to adapt to changing production needs.
Innovation Solution
A vibrating apparatus using a planar motor with magnetic coupling between a mobile and base body, allowing frictionless movement and enabling easy reconfiguration of vibrational parameters through programmable control, without the need for complex mechanical adjustments or heavy damping systems.

Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional vibrating apparatuses use mechanical connection elements (elastic elements) to support conveying members, then the apparatus can convey objects, but friction is generated causing particulate matter production
Solution Approach 1:
The patent replaces the conventional mechanical vibration generation system (coils, magnets, elastic elements) with a piezoelectric system. The piezoelectric elements convert electrical signals directly into mechanical vibrations of the conveying member without physical contact or friction, eliminating particulate matter generation while maintaining reliable operation in aseptic environments.
Solution Approach 2:
The patent introduces piezoelectric elements as an intermediary between the electrical control system and the conveying member. These elements generate vibrations through piezoelectric effect without requiring direct mechanical connection or contact with the conveying member, thus avoiding friction and particulate generation while transmitting vibrational energy effectively.
2Adaptability or versatility
If the mechanical connection elements are sized for specific vibrational parameters, then the conveying member can be driven, but the design becomes rigid and costly to reconfigure
Solution Approach 1:
The patent employs piezoelectric elements that can dynamically adjust their vibrational characteristics (frequency, amplitude) by changing electrical input parameters without any mechanical reconfiguration. This dynamic control capability allows the system to adapt to different conveying requirements simply through software or control parameter changes, eliminating the need for physical adjustments or redesign.
Solution Approach 2:
The patent utilizes the ability of piezoelectric elements to change their operational parameters (vibration frequency, amplitude, pattern) by modifying electrical signals. This allows flexible adaptation to different object sizes, weights, and conveying speeds without altering the mechanical structure, thereby simplifying the design and reducing reconfiguration costs.
3Weight of stationary object
If the frame is provided with strong base and damping members to prevent vibration transmission, then vibrations are damped, but the frame mass increases significantly
Solution Approach 1:
The patent replaces the heavy mechanical damping system (strong base, damping members) with piezoelectric elements that generate vibrations in a controlled manner. Since the piezoelectric system generates vibrations directly in the conveying member without requiring heavy support structures, the frame can be much lighter while still effectively containing vibrations through precise electronic control rather than mass-based damping.
